WARP-SUPPORTIN G MEANS FOR WARP-TWISTING-IN MACHINES.

Application filed January 26, 1928. Serial No. 249,510.

In warp twisting-in machines (see my Patent No. 1,403,067) the upwardlyextending warp ends are clamped in carriages which are normallyspring-urged horizontally outward as far as a warp-holding means againstwhich the'warps bear will permit and move inward when said means ismoved inward as the vertically reciprocating structure carrying thecarriages moves downward. This invention contemplates certainimprovements in the construction of the carriages and of thewarp-holding means, designed to lessen the wear on the warps and on thecarriages and their guideways, and also in the means by which themovements of said holdings means are effected. V

In the drawings,

Fig. 1 is a side elevation of the improved machine;

Fig. 2 is a plan,partly broken away, of its carriage-includingsuperstructure;

Fig. 3 is a front elevation thereof, partly shown in section;

Fig. 4 a rear elevation, with the carriages removed; and

Figs. 5 and 6 details showing the warpholding means and its actuator.

Except as hereinafter noted the following parts are or may besubstantially as heretofore: The frame 1 having fixed bars 2 over whichthe warps extend toward each other; the vertically reciprocatingstructure 3 on the top portion of which the warp clamping carriagesslide, as will appear, and having a pair of rods ito overlie the warps;the fork 5 under and upwardly between whose members the two warps Aextend; the twisting mechanism 6 with its thread-severing means 7 thepairs of reciprocating hookbars 8 adapted to be turned a half-revolutionon each outward movement so that each pair, which maintains a lease orcross in each warp, will release the outermost thread thereof; theoscillating finger 9 for separating such threads from their warps sothat the spiral 10 can then feed them to the twisting mechanism 6; andthe mechanism (partly shown at the right in Fig. 1) for causing thenecessary cooperative functioning of those of theforegoing parts whichhave movement.

Structure 3 has a horizontal arm 11 whose longitudinal opening 11contains a pair of fixed guide-rods 12 on which are springs 13 abuttinga fixed block 14. This arm has a pair of top rails 15 and an underneathabutted by its spring 13, has a pair of peripherally grooved rollers 18receiving a top rail 15 and also a pair of rollers 18 bearing againstthe lower edge-portion of the arm 11. Thus each carriage is adapted notonly to move true and with the least amount of friction but is firmlysupported, on account of the tongue and groove connection in effectexisting between its rollers 18 and rail 15, against the downward pullof the warps, which is considerable when the machine is in operation andthe warps under tension. The presser member 19 is pivoted at 19 to bodypart 17 and it and the warpgripping pads 20 thereof and of the body partare substantially the same as heretofore. The clip 21, pivoted at 21 hasin its recess 22 which receives the spring lug 19 aflixed to the pressermember, a roller 21?, which without friction rides upon said body whenthe clip is hooked over the same to cause clamping of the warp.

The warp-holding means comprises a slide 23 which moves in the groove 16and has its inner end forked and straddling structure 3 and at its outerend has a stop for both warps comprising a shaft 24 fixed in a clip 25and a roller 26 journaled on each end of the shaft. The rollers engagethe warps, and since they are free to rotate they avoid chafing thereof.The inward shifting of the holding means is accomplished by a cam 27which is formed with a yoke 28 which has a bearing 28 on the front faceof frame 1, the yoke being for this purpose apertured to receivestructure 3, and setscrews 28 to bind against the opposite face;

this cam engages the roller 23 on the slide.

Being mounted as described it has a solid and secure connection with theframe.

Having thus fully described my invention, what I claim is:

In a warp twisting-in machine, the combination of the frame a structurevertically reciprocating therein, a warp-clamping carriage normallyurged substantially horizontally along a part of said structure with thetensionedwarps depending therefrom,

warp-holding means movable horizontally contrary to the carriage, and acam to move sa1d means on each reclprocatlon of said structure, said camhaving a jaw hearing against one face of the frame and a screw 1 bearingagainst the opposite face of the frame and coacting With the jaw to bindthe camv to the frame.

In testimony whereof I aflix my signature.

JOHN H. BECKER.
